.tion in such an apparatus of a corrodingchambers of the respective sets.

My invention also consists in certain other features and combinations shown in the drawings and hereinafter more fully described.

The accompanying drawings, which are referred to herein and form a part hereof, illustrate one form of my present invention and serve, in connection with the description herein, to explain the principles thereof and the best mode contemplated by me of carrying those principles into effect.

Of the drawings, Figure 1 is a diagram matic plan view illustrating the relative arrangement of the parts forming the complete apparatus. Fig. 2 is a side elevation of v one of the mechanisms for advancing the supports 1n the corrodmg-chambers, together with the carriage upon which said mechanism is mounted. Flg. 3 1s a vertical long1 tudinal section of the same. Fig. 4 is an end view of the same, certain parts of the device being shown in section to more clearly illus trate certain details; and Fig. 5 is a sectional plan view illustrating certain details of the mechanism.

Like reference-numerals refer to like parts wherever they appear throughout the several views.

first to the general view of the apparatus illustrated in Fig. 1, the two sets of corrodingchambers are represented by numerals 1 and 2, respectively, the corroding-chambers in each set being, as shown, for convenience arranged in pairs. The respective pairs of corroding-chambers are separated by alleyways 3 and 4, in which the various pipes for supplying corroding gases and vapors to the corroding-chambers are arranged. Each of the corroding-chambers is constructed to be opened at-each end, and the two sets of corroding-chambers are oppositely arranged with relation to each other, so that one end of each corroding-chamber opens into the space between the sets. At each of the farther or outer ends of the sets of corroding-v chambers is arran ed a suitable mechanism, generally indicated by the numeral 5, for ad vancing the supports for the comminuted lead into the respective corroding-chambers,

Referring to the drawings in detail and at 1 they are delivered from the corroding-cham= bers and remove the corroded product therefrom. The specific construction of this washing-machine forms no part of my resent invention. As indicated in the raw-v ings, it consists of a platform 9, on which the supports containing the corroded product are received, and an endless conveyer 10 for advancing the supports beneath a series of scrubbing devices 1 1. After passing the scrubbing devices 11 the sup orts are delivered on a suitable carrying evice, the same, as shown, consisting of a car 12, which is mounted upon a track 18, extending in both directions along the sides of the corroding-chambers and transversely outside of and parallel with the'tracks 7, so that the supports may be readily transferred to either of the mechanisms 5 foradvancing the same into the corroding-chamber with a new char e'of comminuted lead. The corroded product, which is removed from the supports by the scrubbers 11, is carried to the opposite end 'of the machine, where it is received-by a screening device 14, from which it passes, together with the water in which it is suspended, to suitable settling-tanks. (Not shown.)

The details of the mechanism for advancing the supports into the corroding-chambers are illustrated in detail in Figs. 2 to 5, inclusive, and will now be specifically described; In the embodiment of this feature of the apparatus illustrated the carriage 6 consists of a base-frame 15, substantially rectangular in form and carrying at its four corners suitable standards 16. These standards 16 are hollow, (see Fig. 4,) the same being constructed to receive corresponding tubular uprights 17, which carry at their upper ends a rectangular frame 18. Suspended from the frame 18 by means of the vertical posts 19 is a similar frame 20, and suspended from the frame 20 by the posts 21 is a lower frame consisting of longitudinal bars 22 and transverse girders 23, the latter being extended, as shown in Fig. 4, and provided with grooves adapted to engage the guiding-ribs 24, provided on each of the standards 16. Mounted on the side bars 22 by means of the two sets of brackets 25 and 26 are suitable upper and lower guide-rails 27 and 28, adapted to receive the supports 29 for the comminuted lead. The supports 29 preferably and as shown consist of suitable trays adapted when placed end to end to form a continuous reticulated support, on which the comminuted lead may be uniformly subjected to the action of the corroding-gases in the corroding-chamber. As shown, each of these trays consists of a series of parallel bars 29,

'which are arranged to extend transversely of the advancing mechanism and of the corroding-chambers, said bars being secured at their opposite ends by the longitudinal bars 80 and 31. Any suitable means may be provided for advancing the trays along the guides 27 and 28 and onto the ways 32 in the corrodingchamber. As shown, this means consist of a pair of endless chains 33, which are mounted near the ends of suitable transverse shafts 34, journaled in the side bars 22. The upper stretches of the two chains are arranged pposite the space between the guides 27 and 28, and the two chains are connected at suitable intervals by means of transverse pushers which, as shown, consist of angle-bars 35, adapted to pass between the guides 27 and 28 and engage the rear ends of the successive trays.

In order that the guides 27 and 28, togetherwith the parts cooperating therewith, may be adjusted vertically in order to bring them into cooperative relation with the various ways in the corroding-chambers, suit able means are provided to raise and lower the posts 17, together with the parts suspended therefrom. The means shown consist of a series of vertical screw-threaded shafts 36, centrally located in the standards 16 and adapted to engage suitable nuts 37, carried by thelower' ends of the post 17. Any suitable means may be provided for turning the shafts 36 in unison. As shown, each of the shafts is provided at itsv lower end with a beveled gear 38, which gears are adapted to mesh with corresponding beveled gears 39'. The beveled gears 39 are mounted on transverse shafts, those at the forward end of the machine being fixed to shaft 40 andthose at the rear end of the machine to the-shaft 41. The two shafts 40 and 41 are connected to rotate in unison by a chain 42, mounted onsuitable sprockets 43. and 44. The shaft 40 is driven by chain 45, which receives motion from a short transverse shaft 46, mounted at an intermediate point on the base-frame 15 and journaled at one end on one of the side bars of the frame 15 and at the other end on an intermediate bar 47 of said frame. The shaft 46 receives motion from the powershaft 48, which may be driven by any suitable motor by chains 49 and 50, which are mounted on suitable sprockets on the shafts 46 and 48 and an intermediate shaft 51. In order that the power-shaft 48 and the intermediate shaft 51 may be rotated independently of the shaft 46 for a purpose presently to be explained, a suitable disconnecting device is provided between the shafts 46 and 51. As shown, the disconnecting device consists of a clutch 52, arranged between the shaft 46 and the spocket-wheel which receives motion from the chain 49. The clutch 52 may be operated by any suitable means, as by a hand-lever 53.

The chains 33 may be driven from the power-shaft 48 by any suitable means. As shown, the shaft 34 is driven from an intermediate shaft 54 by a air of chains 55 and 56 which are mounted on suitable sprockets, arranged with the outer ends of each of said shafts. The shaft 54 is journaled in the side bars 22 and is provided at one-end with a worm-wheel 57, which is adapted to mesh with a suitable worm 58. In order that the pushing mechanism carried by the bars 22 may be raised and lowered without interrupting the driving connections for the chains 33, the worm 58 is loosely keyed to a vertical shaft 59, which is adapted to slide loosely through the bearings 60 and 61 on the bar 22, between which bearings the worm 58 is confined. The shaft 59 is journaled at its lower end in a suitable bracket 62, carried by the base-frame 15, and is geared to the shaft 51 by suitable beveled gears 63. In order that the raising and lowering mechanism may be operated independently of the pushing-chains 33, a suitable disconnecting device is arranged between the shaft 58 and the shaft 59. As shown, a clutch 64 is located between the shaft 51 and the gears 63, which clutch may be operated by a suitable lever 64.

In order that the comminuted lead may be fed onto the trays as they are advanced into the corroding-chamber and that it may be fed thereto in an uncompacted condition, the means whereby the lead is comminuted is preferably carried with the tray-advancing mechanism and is so arranged as to feed the comminuted lead directly onto the trays. To this end a melting-pot 65, from which the molten lead is delivered. in suitable fine streams through a suitable perforated plate 66, is mounted on the frame 20. Preferably and. as shown the pot is arranged at the end of the frame farthest from the corrodingchambers, and the delivery-spouts, with the erforated plates 66, are so arranged as to deliver the lead onto the trays as they pass from the guides 27 and 28 into the corrodingchamber. 67 represents suitable burners by which the melting-pot is heated. The frame 20 is provided at its opposite sides with suitable platforms 68, having hand-rails 69. For the purpose of guiding the outer streams of lead onto the trays suitable shields 70 are provided at the sides above and at the forward end of the guides 27.

When the lead in any of the corrodingchambers has been completely corroded, the ends of the chamber are opened and the mechanism for advancing the trays into the chamber is brought into cooperative relation therewith. The melting-pot having been suitably heated and the guides 27 and 28 having been brought into alinement with either the upper or the lower set of ways 32, the pushing-chains 33 are started. The trays which are supplied to the outer or feed ends of the guides by hand from one of the cars 12 are then advanced into the corroding-chamber, carrying in with them a suitable layer of the comminuted metal. As the new line of &

trays are advanced into the corroding-chamber the trays which contain the corroded product are pushed therethrough and are delivered one by one at the opposite end of the chamber, from whence they are transferred to the platform 9 of the washing-machine. While the trays containing the product are usually transferred to the washing-machine by hand, it is obvious that a suitable carrying device may be provided for this purpose, if desired. When the new line of trays.is advanced the full length of the corrodinging-chamber, the advancing mechanism is stopped and is moved vertically into line with the next tier of trays, these operations being accomplished by suitable manipulation of the clutches 52 and 64. The advancing mechanism is then set into motion, and the above-described operations are repeated. When the corroding-chamber is completely filled with a new charge of comminuted lead, it is closed up and the corroding-gases are admitted thereto, the advancing mechanism being moved by means of a carriage 6 to another corroding-chamber in which the product has been completely corroded. By mounting the means for comminuting the lead on the vertically-adjustable frame the proper cooperative relation between the comminuting means and the trays as they are being advanced into the corroding-chamhers is always maintained, so that the comminuted lead is delivered in precisely the same condition upon each of the tiers of trays. In this way the entire charge of metal in each corroding-chamber is uniformly subjected to the action of the corroding-gases and an even corrosion of the metal is insured.

My invention in its broader aspects is not limited to the precise construction shown, nor to the particular construction by which it is carried into effect, as many changes may be made in the construction without departing from the main principles of the invention and without sacrificing its chief advantages.
